    that can still lead back to the advance plate,,,,as soon as you hit the gas pedal, the carb sends a vacuum signal to the vacuum advance for it to move the breaker plate and points,,,,something could be loose in that area,,,,

    Went back out ...yes when I pull the plate running badly. I could only pull 7 on the vacumm gage when running but definatly the problem. I lubes the contact points on the plate also moves freely.

    that sounds like a ground problem,,,,,the points need to be grounded,,,sometimes you need a little ground wire to ground that breaker plate to the base if you cant fix it
